Astronomers have discovered evidence that could help solve a long standing dispute over the origin of Type Ia supernovae, by observing the youngest example of the titanic explosions located to date.

Type Ia supernovae result from a white dwarf exceeding 1.4 solar masses after accreting hydrogen from a companion star, leading to a thermonuclear explosion. The Sirius system contains a white dwarf ...

An explosion seen in the cosmos in the early 1600s may actually be an "Alien Type Ia supernova", according to a new paper. In October 1604, astronomer and mathematician Johannes Kepler spotted a new ...

When most people hear the word supernova, they envision a massive star reaching the end of its life and exploding outwards to leave a ghostly remnant in its place. This is called a Type II supernova — ...

WASHINGTON (Reuters) -The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its nuclear fuel ...
